I opposed to this wording in there as well.

If one deploys a 6500/7600/SUP720 and configures IPv6 on it today, it'll 
slow-path every IPv6 packet with a fragmentation header. Default 
behaviour.

I have no idea how much of the behaviour your're seeing is caused by this 
default behaviour, but I'd venture to guess a lot.

Oki, I haven't seen these.
